Hmmm, do you like to root an OC3 with heavy traffic ??? 

I have a client with a 34 MBit and the Roter is an old K5 166 with 
32 MByte of memory... The monthly middle is arround 1.3 MByte/Second

Can be done with a 486/100 and LRP <http://www.linuxrouter.org> 
which is based on Debian.

I have done this before, blocked all ports and have done Portforwarding 
to the Servers. Never I have had problems...
